Continuity mistake: After Ellis and his mom are stopped by the Troopers, one of them holds a clip board with Mud's picture on it and finger prints. As he is showing it to Ellis, the close up shows his fingers over the finger prints as he is holding it one-handed. Then in a further shot, his fingers are suddenly holding the board about 2 inches above the finger prints. (00:38:40)
Continuity mistake: Once Mud reveals who he shot and asks for Neckbone and Ellis to help him get the boat out of the tree, Neck asks for the pistol in return. Mud reaches around his back and puts his hand on the handle of the pistol tucked in the back of his jeans as he begins saying his shirt and pistol are the only things of value he has. It cuts to a close up, and suddenly his hand is on his hip and he reaches for his shirt, then back around to his pistol again. (00:43:50)
Continuity mistake: After telling Ellis the bonfire is for good luck, he and Mud begin walking back towards Ellis' boat. As Mud says "You don't know his story" they are in shadows of trees about to walk out into the clearing, but there are bushes in the way. The angle cuts with Ellis saying "I don't care" and suddenly they are out in the sunlight in the clearing, and the bushes they were walking up on have vanished. (01:11:05)
Continuity mistake: When Neckbone calls Mud for help after Ellis falls into the snakepit, Mud grabs his shirt off the limb, sticks his arms in, and takes off running with the shirt unbuttoned. In the next shot as Mud runs towards the camera, his shirt is fully buttoned.
Continuity mistake: When Ellis falls in the snake pit, a snake crawls around his throat. A frame later, from a different angle, the snake is gone.
